Abstract: An electrically and manually adjustable screening device for screening a window. The screening device has a screen with a variable length and a positionable free end. The longitudinal position of the free end determines the length of the screen. An electric drive is operably connected to the screen for adjusting the longitudinal position of said free end. A sensor arrangement is configured to detect manual movement of the longitudinal position of the free end and for outputting a detection signal. A circuit or processor is configured to control the speed of the electric drive and is configured to ramp up the speed of the electric drive in response to a detected manual movement starting the ramp up at a speed similar to the speed of the detected movement to gradually take over from the manual movement.

Abstract: The invention concerns a linear compressor, particularly a refrigerant compressor, with a housing (2, 2?) and a compression unit, which comprises a compressor with a piston and a cylinder as well as a linear motor driving the piston in relation to the cylinder along a movement axis, the compression unit (30) being connected to the housing (2) via a spring arrangement (7). It is endeavoured to provide a space saving support of the compression unit (30) in the housing that enables good vibration suppression. For this purpose, the spring arrangement comprises a spring (6, 7), which is curved in the circumferential direction in relation to the movement axis (50), said spring surrounding the compression unit (3-5) on at least a share of its circumference.

Abstract: The invention concerns a suction muffler for a hermetic refrigerant compressor with a housing having an inlet and an outlet and limiting at least one muffling chamber, and a gas supply channel located in the muffling chamber between the inlet and the outlet. It is endeavoured to prevent too much oil from remaining in the refrigerant gas flow. For this purpose, the gas supply channel forms a throttling path and ends in the muffling chamber, and that in the area of the inlet of the gas supply channel an oil extraction opening is located, which ends in the muffling chamber.

Abstract: A data processing system including a buffer for temporarily maintaining a portion of a plurality of compressed data streams and a switch. Each portion of the compressed stream comprises one or more units of an encoded media signal. The switch provides selective connectivity between the buffer and a plurality of processors. The plurality of processors can be configured to analyze the one or more units of the encoded media signal in the buffer to generate statistical data about the encoded media signal.

Abstract: The invention concerns a linear compressor (1) with a piston (16) reciprocating in a cylinder (8), a linear motor acting upon the piston (16) and a resonance spring arrangement (5) connected with the piston (16). It is endeavoured to reliably avoid damaging the compressor during operation. For this purpose, the resonance spring arrangement (5) has a fixed stop (48) allocated to the upper dead point of the piston (16).

Abstract: The invention concerns a linear compressor (1), particularly a refrigerant compressor, with a compression unit (3) having a cylinder (8) and a piston (16) reciprocating in the cylinder (8), and a linear motor (4) having an outer stator (18), an inner stator (20) and an armature (22) located in a gap (21) formed between the outer stator (18) and the inner stator (20), the armature (22) being connected to the piston (16) via a piston rod (28). It is endeavoured to design such a linear compressor in a simple manner with the smallest possible dimensions. For this purpose, it is ensured that the armature (22) is connected to the piston rod (28) inside the axial length of the inner stator (20).

Abstract: A suction sound damper for a hermetically encapsulated compressor has a housing that is formed of at least an upper part (3), a lower part (1) and an insert (2), and having at least two chambers (7, 8) and a channel (9), connected thereto, leading from a lower inlet opening (10) to an upper outlet opening (11). The insert (2) has a side wall (18) which, together with a section (19) of the housing wall, forms a capillary gap (20) in which lubricating oil collects and is retained. This produces additional sound damping.

Abstract: The invention concerns a connecting rod for a hermetic refrigerating compressor, in which the connecting rod forms the mechanical connection between a crank and a piston. The purpose of the invention is to reduce wear in the crank bearing of the compressor with simple means. This is obtained by reducing compressive stresses in the connecting rod by making a cut-out in the connecting rod near the crank bearing. The cut-out causes deflection of compressive stresses, so that they are distributed over a larger share of the crank bearing surface. Also the outer shape of the connecting rod is adapted, so that also here the compressive stresses are distributed over a larger bearing surface. This reduces the wear on the crank bearing of the compressor and increases the life.
